FERRULE FOR UMBRELLAS, 800.

SPECIFICATION forming part of Letters Patent No. 392,271, dated November6, 1888.

(No model.)

To aZZ whom it may concern.-

Be it known that I, WALTER MARSH J ACK- SON, a resident of New Yorkcity, in the county of New York and State of New York, have inventedcertain new and useful Improvements in Ferrules for Umbrella-Handles andSimilar Articles; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appcrtains to make and use thesame.

My invention relates to an improvement in ferrules, and particularly tosuch as are employed to protect the tip ends of the stickhandles ofumbrellas or parasols.

I-Ieretofore it has been customary to construct the metallicsocket-pieces used as ferrules for umbrellas and like articles fromsheet metal, which is drawn in tubular form with open ends, the ferrulebeing provided with a tip end which has to be affixed in place bybrazing or other similar means, and in order to hold the ferrule inplace a hole is punched through its side wall to receive asuitably-sized nail or brad.

There is considerable work entailed to affix the metal tips in thesheet-metal ferrules that are made as above stated, which enhances thecost of production, and the method of securing the socket or ferrule onthe stick with an inserted brad or small nail is defective and lacksneatness of finish.

One of the objects of my present invention is to construct a ferrulefrom a single blank of sheet metal by drawing it into form through diesor other suitable mechanism, so as to produce a ferrule with a solid'tipend that is integral with the side wall.

A further object is to produce a'tipped ferrule from a sheet-metal blankor planchet in a manner that will afford a thick tip end, whereby it isrendered more durable at the point which is most liable to wear out.

A further object is to furnish an integrallytipped socket or ferrule forumbrellas and like articles with an integral screw-thread at its openend, thus furnishing a neat and secure fastening for attachment of theferrule upon the tip end of the handle-stick.

With these objects in view my invention consists in certain features ofconstruction and combinations of parts,'which will be hereinafterdescribed, and pointed out in the claims.

Referring to the drawings, Figure 1 is aside elevation, in section,through the axial center of the ferrule, showing it in place upon thetip end of an umbrella stick or handle. Figs. 2, 3, 4, 5, and 6 arerepresentations of different steps in the conversion of a planchet ofsheet metal into an integrallytipped socket.

A is a disk or planchet, of sheet metal of suitable thickness to afforda proper tip end to the ferrule, its diameter being proportioned to thedimension of the finished ferrule required.

Proper dies are provided, which consist of perforated plates of steel,the holes in said dies being graduated in diameter to successively drawthe disk A into a cylinder by the punching of male-dies that are causedto impinge upon the planchet A, suitable powerdriven mechanism beingemployed to facili tate the rapid execution of the work.

The first step in the process of converting the planchet A into aferrule is shown in Fig. 3, in which a rimmed edge is turned upon thecircular disk', and it will be seen that the portion e of said disk orplanchet is left of the same thickness as before it engaged the firstset of dies.

In Fig. i the disk is further extendedinto a short cylinder, in Fig. 5it is considerably elongated by the third step in the operation, and inFig. 6 the ferrule is shown nearly complete, the side walls beingrendered comparatively thin between the lower end, 0, and the offsetshoulder e, that is formed by the dies that effect this step in themanufacture of the ferrule.

' A completed ferrule is shownin Fig. 1. The offset portion B at theopen end of the ferrule is threaded internally to engageaproperlypointed handle of an umbrella, parasol,or cane, as the case maybe,

As the handles of umbrellas are usually made of hard wood, if the threadin the socket or ferrule is of rather a fine pitch it will cut acorresponding thread in the wood when it is screwed upon the stick bymeans of a proper instrument or tool, so that when in place asecurefastening is afforded without any unsightly projections being producedon the exterior surface of the ferrule.

It will be noticed that by proper 1nanipulation the integral tip end 0of the finished ferrule is allowed to retain the original thickness ofthe planchet out of which the ferrule was drawn, thus providing asubstantial wearingsurface for the tip end of the umbrella stick orhandle, which is necessary, as in carrying the same it is converted intoa walking-stick or cane, and thus receives considerable wear.

It is evident that the ferrule may be made of any suitable metal, andthat any preferred finish may be given it. Sheet-brassorsheet-steel ispreferred as a material from which to pr0- duce them. I

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. A ferrule for umbrellas and like articles, having an internalshoulder, the portion of the ferrule above said shoulder being screw- 20threaded internally.

2. A ferrule for umbrellas and like articles, havinga closed lower end,an open upper end, and an internal shoulder located at a point betweensaid ends, the portion of the ferrule 25 above said shoulder beingscrew-threaded.

3. A ferrule formed from a single piece of metal and having a closedlower end, an open upper end, and an internal shoulder, the latter beinglocated at a pointbetween said ends. 30

In testimony whereof I have.signed this specification in the presence oftwo subscribing witnesses.
